8 Things We Can Do Now to Build a Space Colony This Century

Before humans start living in space on a regular basis, there's a lot of basic science and political agendas that need to advance. We talked to scientists and experts about the fundamental things they think we should do right now, if we want to have a space colony in the next 100 years. 1. Save Earth NASA astronomer Amy Mainzer, who studies Near Earth Objects at JPL, says our number one priority has to be here on our home planet. Amy Mainzer is an astrophysicist at the Jet Propulsion Lab who builds instruments for space… She told io9 that it's a pretty inhospitable universe out there, so our space colonies will probably never replace home:
From my perspective, the most important thing we can do to be prepared for any activity far in the future is try not to wipe out life here. Indiscriminate environmental destruction and the practice of rendering entire species extinct cannot continue if we want to have a long-term future either in space or on Earth. As an astronomer, I spend a lot of time thinking about other places than Earth, and they are not particularly hospitable. It's pretty clear that the vast majority of humanity will stay here. Therefore, I'd say that the defining challenge of the next hundred years is to come to grips with creating a sustainable future here, as a minimum precursor to building a sustainable future anywhere else.
